When does visual perceptual grouping affect multisensory integration?

Several studies have shown that the direction in which a visual apparent motion stream moves can influence the perceived direction of an auditory apparent motion stream (an effect known as crossmodal dynamic capture). However, little is known about the role that intramodal perceptual grouping processes play in the multisensory integration of motion information. The present study was designed to investigate the time course of any modulation of the cross-modal dynamic capture effect by the nature of the perceptual grouping taking place within vision. Participants were required to judge the direction of an auditory apparent motion stream while trying to ignore visual apparent motion streams presented in a variety of different configurations. Our results demonstrate that the cross-modal dynamic capture effect was influenced more by visual perceptual grouping when the conditions for intramodal perceptual grouping were set up prior to the presentation of the audiovisual apparent motion stimuli. However, no such modulation occurred when the visual perceptual grouping manipulation was established at the same time as or after the presentation of the audiovisual stimuli. These results highlight the importance of the unimodal perceptual organization of sensory information to the manifestation of multisensory integration.     

Apocalyptic Eschatology: Lutheran‐Pentecostal Reflections on the End

This paper initiates a Lutheran‐Pentecostal conversation around the topic of apocalyptic eschatology. Both groups have deep historical commitments to the apocalyptic theology of the Bible, even though they often have expressed these commitments in vastly different ways. We offer a historical and constructive outline of Lutheran apocalyptic eschatology, drawing attention to points of consonance and dissonance vis‐à‐vis Pentecostal forms of eschatology. We conclude with a series of generative questions that are meant to shape future Lutheran‐Pentecostal exchanges.     

Linking Adult Attachment Styles to Relationship Satisfaction in Hong Kong and the United States: The Mediating Role of Personal and Structural Commitment

Maintaining a satisfying heterosexual relationship is important to many individuals?? happiness and physical health. Evolutionary theories on the formation of relationships suggest that adult attachment and relationship commitment are universal mechanisms for securing and maintaining such mating relationships. This study sought to understand how these two mechanisms may link to each other and how they in turn contribute to relationship satisfaction with one??s current partner in Hong Kong Chinese and American cultures. Similarities in the model for relationship satisfaction were found among young dating couples in the United States and Hong Kong. Specifically, attachment anxiety was positively linked to structural commitment, whereas attachment avoidance was negatively related to personal commitment. Both dimensions of attachment (anxiety and avoidance) and both components of commitment (personal and structural) were found to predict current relationship satisfaction significantly and equivalently across cultures, with the pathway from attachment avoidance to current relationship satisfaction similarly mediated by personal commitment in both cultural groups. These results were interpreted in terms of a probable universal logic informing the interpersonal dynamics involving attachment and relationship commitment.     

注意捕获的另一扇窗户——无意视盲

观察者集中注意于某个物体或事件的时候,他们经常不能觉察到显著的、与众不同的物体,这种现象被称为“无意视盲”（Inattentional Blindness）。在无意视盲研究中,存在两类实验范式——静态无意视盲和动态无意视盲研究范式。首先,从刺激的感觉显著性、认知显著性、心理工作负荷、定势和期望以及加工能力等方面分析了影响无意视盲的因素;其次,对无意视盲和无意遗忘的争议以及无意视盲是“全或无”还是连续谱的争议也进行了总结;最后,从无意视盲角度出发探讨了内隐注意捕获和外显注意捕获之间的关系     

Perceiving the vertical distances of surfaces by means of a hand-held probe.

Nine experiments were conducted on the haptic capacity of people to perceive the distances of horizontal surfaces solely on the basis of mechanical stimulation resulting from contacting the surfaces with a vertically held rod. Participants touched target surfaces with rods inside a wooden cabinet and reported the perceived surface location with an indicator outside the cabinet. The target surface, rod, and the participant's hand were occluded, and the sound produced in exploration was muffled. Properties of the probe (length, mass, moment of inertia, center of mass, and shape) were manipulated, along with surface distance and the method and angle of probing. Results suggest that for the most common method of probing, namely, tapping, perceived vertical distance is specific to a particular relation among the rotational inertia of the probe, the distance of the point of contact with the surface from the probe's center of percussion, and the inclination at contact of the probe to the surface. They also suggest that the probe length and the distance probed are independently perceivable. The results were discussed in terms of information specificity versus percept-percept coupling and parallels between selective attention in haptic and visual perception.     

Universals and cultural differences in the judgments of facial expressions of emotion

We present here new evidence of cross-cultural agreement in the judgement of facial expression. Subjects in 10 cultures performed a more complex judgment task than has been used in previous cross-cultural studies. Instead of limiting the subjects to selecting only one emotion term for each expression, this task allowed them to indicate that multiple emotions were evident and the intensity of each emotion. Agreement was very high across cultures about which emotion was the most intense. The 10 cultures also agreed about the second most intense emotion signaled by an expression and about the relative intensity among expressions of the same emotion. However, cultural differences were found in judgments of the absolute level of emotional intensity.     

Old and new controversies in the alternative treatment of attention-deficit hyperactivity disorder

Use of complementary and alternative medicine (CAM) for treatment of attention-deficit hyperactivity disorder (ADHD) has become widespread in both referral and primary care populations. We review the purported mechanism of action and available evidence for selected CAM therapies for ADHD. Enduring controversies, such as elimination of artificial food additives, colors, and/or preservatives; the effect of sugar on behavior in children; and the use of EEG biofeedback, have been well studied but lack support as effective sole treatments for ADHD. The initial evidence for some emerging CAM therapies, such as essential fatty acid supplementation, yoga, massage, homeopathy, and green outdoor spaces, suggests potential benefits as part of an overall ADHD treatment plan. More rigorously designed studies are needed to evaluate their effectiveness as single therapy for ADHD.     

Intergroup Perceptions and Attitudes toward Immigrants in a Culturally Plural Society

The research examined perceptions of Chinese immigrants held by New Zealanders of European and Maori descent. The study (N = 318) adopted an intergroup perspective to test a predictive model of attitudes toward immigrants. It was based on a nation‐wide survey with prospective respondents randomly selected from the New Zealand Electoral rolls. Findings revealed that Maori differed from their European counterparts in predictable ways, reporting more relative deprivation and greater perceived threat, and holding more negative outgroup attitudes. Less contact and greater perceived threat predicted more negative attitudes toward immigrants; in addition, when intergroup boundaries were permeable, the link between perceived threat and negative attitudes was stronger in Maori than New Zealand Europeans. While intergroup relations are traditionally analysed in a dual group formation involving a privileged “dominant” ingroup and disadvantaged “minority” immigrant outgroup, the current research suggests the need to advance beyond this dichotomy to a more inclusive approach and to consider the interface between the historical and political milieux in specific national contexts.     

Mapping Residents' Perceptions of Neighborhood Boundaries: A Methodological Note

Neighborhood influences on children and youth are the subjects of increasing numbers of studies, but there is concern that these investigations may be biased, because they typically rely on census-based units as proxies for neighborhoods. This pilot study tested several methods of defining neighborhood units based on maps drawn by residents, and compared the results with census definitions of neighborhoods. When residents' maps were used to create neighborhood boundary definitions, the resulting units covered different space and produced different social indicator values than did census-defined units. Residents' agreement about their neighborhoods' boundaries differed among the neighborhoods studied. This pilot study suggests that discrepancies between researcher and resident-defined neighborhoods are a possible source of bias in studies of neighborhood effects.     

Structural equation modeling with heavy tailed distributions

Data in social and behavioral sciences typically possess heavy tails. Structural equation modeling is commonly used in analyzing interrelations among variables of such data. Classical methods for structural equation modeling fit a proposed model to the sample covariance matrix, which can lead to very inefficient parameter estimates. By fitting a structural model to a robust covariance matrix for data with heavy tails, one generally gets more efficient parameter estimates. Because many robust procedures are available, we propose using the empirical efficiency of a set of invariant parameter estimates in identifying an optimal robust procedure. Within the class of elliptical distributions, analytical results show that the robust procedure leading to the most efficient parameter estimates also yields a most powerful test statistic. Examples illustrate the merit of the proposed procedure. The relevance of this procedure to data analysis in a broader context is noted.
